What is the reason for loud engine noise and slow acceleration?
2 Answers
Loud engine noise and slow acceleration are caused by issues with the timing belt and valve clearance. Timing Belt Fault: If the timing belt is off by one tooth, the engine sound will be abnormal. The noise at high RPMs will be very loud, and there may be difficulty starting the engine. Immediate repair is necessary to avoid damaging the engine. Valve Clearance Fault: If the valve clearance is too small, the engine will lack power and produce a muffled sound. If the valve clearance is too large, there will be significant noise and difficulty starting. This issue is related to the engine's configuration. It is recommended to visit a reliable auto repair shop to adjust the engine configuration.
I think it's quite common to experience loud engine noise and slow acceleration. The main reason could be severe carbon buildup blocking the intake system or fuel injectors, leading to incomplete combustion and increased operational noise. Additionally, aging spark plugs or ignition system issues can also cause a sluggish feeling during acceleration. This has happened to me a few times while driving, and ignoring it may affect engine lifespan or even cause a sharp increase in fuel consumption. As for solutions, you can first check the carbon buildup situation. If it's minor, you can add some fuel additives and drive on the highway to clean it out. However, if it's severe, you'll need to visit a professional repair shop for disassembly and cleaning. Remember to perform regular maintenance, especially if you drive frequently in areas with poor air quality where carbon buildup tends to accumulate. Keeping up with regular cleaning can make your car run smoother and prevent small issues from turning into major headaches. Addressing problems promptly can also reduce risks during long-distance trips.
